    Object Number: 171212  Size: SH
  5. Install the lower control arm ball joint stud into the suspension knuckle.
  6. It may be necessary to use an allen wrench to keep ball joint stud from spinning while tightening the ball joint stud nut.

    Tighten

      Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

    1. Tighten the lower control arm ball joint stud nut to 20 N·m (15 lb ft) to seat the ball joint stud.
    2. Turn the nut an additional 31/2 flats.
    3. Check the ball joint stud nut for a minimum final torque of 55 N·m (41 lb ft).
